VHAAS AND HILFORD B. FERGUSON, OF BROOKLYN, NEW YORK. l

WBAPPING MACHINE.

Application led Hay 12,-1922. Serial No. 560,365.

To` all whom t may concern:

Be it known that we, EDWARD HAAs and MILroRD B. FERGUSON, citizens ofthe United States, residing at Brooklyn, in the county of Kings, intheState of New York,

have invented certain new and useful Improvements in Wrapping Machines,of' which the following is a specification.

The invention relatesdto wrapping machines and more particularly to'wrapping machines of thetype in vwhich `the articles to be enclosed inone or more wrappers are advanced through thev machine by :successivestao'es, and in which the various wra per fdlding operations areperformed as the articles pass from lone stage to the next or while theyare momentarily atrest.

The object of the invention is to improve upon the' construction andmode of operation of wrapping machines of the above type in order that`the wrapping operations may be more eX editiously and eiiicientlyperformed.

through the machine. Cooperating with' the transport system are.improved means for performing the various wrapper folding operations.

The improved transport syste-m comprlses a series of 'intermittentlymovable carriers on which are mounted a series 'of equally spacedpockets for holding the articles to be wrapped. During the operation ofenclosing the article in the wrapper, the article and its wrapper arefirst inserted in a pocket of one carrier, which movement partiallyencloses the article in the wrapper.

The partially wrapped article is then transferredto a pocket of asecondA carrier. The end extensions of the wrapper are left projectingbeyond the ends of the pocket; The article vwhile it is in the secondpocket passed between end foldersl by which the end extensions of the`wrapper are folded down against the side folds of the wrapped article.In order that the end folds may be laid directly against the article,one wall of the pocket is made substanti ally shorter than the article.Fold breakers are provided to perform the usual function of the removedends of the pocket wall. Upon the completion of the wrapper foldingoperations the wrapped article is returned to the To t is end theinvent'ion'con-v templates a rearrangement .ofthe transport. system bywhich the articles are advanced first carrier, and preferably to thesame `pocket on the 4first' carrier in which itl was ori 'nallyinserted.

7hile the wrapped article is be' transferred from the second carrier tot e first carrier it ushes into the pocket of the latter a label w ichhas Abeen positioned between the two pockets. The labels are fed intothe .machine one at a time by any preferred label feeding means. Thelabels are then transferred from the point at which they are deliveredto the machine to the point where they are Aengaged by the wrapped`article and carried into the pocket by which the label is partiallyfolded Vabout the article. The label transfer comprises means forgripping and positively holding 'the label, means for properlypositioning the label between the two alinedpockets, and means forreleasingl the label. In the preferred form of the invention the pocketwhich holds Athe wrapped article comes to rest so that the article is ona vertical Vplane with its longitudinal axis horizontally disposed. 'Theopposite alined pocket is positioned below the article, so that thewrapped article is pushed downwardly, carrying the label with it intothc'lower pocket. Thus the means for transferring the label from wrappedartic e is completed by transferof the label about Athe rin the wrappedand partially labeled ary tic e to a pocket of a third carrier, wherethe wrapped'and labeled article remains a sulficient length of time forthe glue to set. It

isthen discharged from the carrier onto a' receiving platformby which itisinserted into a stacking chute which retains the articles until theyare removed by the operator. The means for receiving and stack' ing' thewrapped and labeled articles comprise a chute having a yieldinglymounted bottom by which the stacked .articles are supported and aswinging platform for inserting each newly wra ped and labeled articleinto the bottom o the chute.

The preferred form of the invention is illustrated in the accompanyingdrawings, in which Fig. 1 is a longitudinal vertical section taken onthe line 1--1 of Fig. 2; Fig. 2 is a horizontal section taken on theline 2-2 of Fig. 1; Fig. 3 is an elevation of the left hand end of themachine; F 4 is a section taken on the line 4 4 of ig. 3; Fig. 5 is afront elevation of the machine, with certain parts removed; Fig. 6 is a.diagrammatic view of the transport system the arrows; Fig. 10 is a planof the label transferring device; Fig. 11 is a section taken on the line11-11 of Fig. 10, but with the movable parts turned at an angle of 90;Fig. l2 is a transverse section across the label guide; Fig. 13 is aplan of the stacking chute, showing its relation to the third carrier; Fig. 14 is a section taken on the line 14-14 of Fig. 13; Fig. 15 is asection taken on the line 15-15 of F ig. 14; Figs.. 16, 17, 18, 19 and20 illustrate the various stages of enclosing the article in the inner`wrapper and then in the label; Fig. 21 is a vperspective view of thewrapped article; and Fig. 22 is a perspective view of the wrapped andlabeled article.

The improved wrapping machine com-- prises in general means for feedingthe articles to be wrapped one at a time to the machine; means forplacing an inner wrapper in the path of .travel of the article into themachine; a series of pockets adapted to hold the articlesbeing wrappedmounted on intermittently movable carriers; a series of plungers forinsertin the articles into and ejecting the articles From the pockets;end foldin devices cooperatin with the plung- 'ers an the pockets for foding the ends of the wrapper about the article.; means for supplying alabel to the machine and forv the drawings, comprises a transport systemfor transporting the articles to be wrapped throughthe machine for thevarious wrapping operations. This transport system includes a series ofintermittently movable carriers on which are mounted the spaced pocketsfor holding the articles to be wrapped and a series of plungers forinserting the articles in the pockets and egecting them therefrom ln thepreferred form of the invention the intermittently movable carriers arearranged one above another and are generally indicated in Fig. 6 by thereference numerals 5, 6 and 7. On carrier 5 is mounted a series ofequally spaced pockets 8, and on carrier 6 is mounted a series ofequally spaced pockets 9 corresponding to pockets 8. On carrier 7 ismounted a series of pockets 10. The carriers travel in the directionsindicated by the arrows in Fig. 6. The article to be wrapped is firstinserted with its wrapper in one of the pockets of carrier 6. Thepartially wrapped article is then transferred to one ofthe pockets ofcarrier 5. While the article is in this pocket, the folding operationson the wrapper are completed. The wrapped article is then returned toone of the pockets of carrier 6 the preferred form of the invention, tothe same pocket). Previous to the transfer of the article from carrier 5to carrier 6, ,a label is positioned between the two alined pockets sothat the insertion of the wrapped article and label into the pocket oncarrier 6 partially folds the label. The partially labeled article isthen transferred to one of the pockets of carrier 7 by which the foldingvof the label is completed and then the wrapped and labeled article isdischarged from the machine.

Thel articles to be wrapped may be supplied to the machine by a conveyeror they ma be stacked in a hopper, as shown at l1 in igs. 1 and 2.Whether a conveyer or a hopper is to be used will depend upon thecharacter of the articles to be wrapped. These devices are of well-knownconstruction and need no detailed description. Briefly, the hopperconsists of an adjustable frame construction supported from the rods 12which extend transversely of the machine and are secured in the frame 13thereof,

which is supported onthe legs 14. The v hopper is openat top and bottom.A reciprocating plunger 15 mounted on the guides 16 passes under thehopper and carries the lowermost article into thepocketof the carrier 6then in alinement therewith. The plunger 15 is actuated from a crank 17(Fig. 5) mounted on the front end of the main cam shaft 18 journaled inthe left hand end of the machine. The crank 17 is connected by a rod 19with one arm 20 of a bell-crank secured to the shaft 21, the other arm22of the bell-crank being connected by a link 23 with the support-24 onwhich the plunger 15 is mounted. y

Previous to the rcciprocation of the plunger 15 which inserts theunwrapped article in the alined pocket of carrier 6, an in ner wrapperis positioned in the path of travel of the article. The roll of paper ortin foil 25, from which the inner wrappers are cut, is mounted on a rod26 supported from brackets 27 secured to the top of the machine. Thestrip of wrapper ma'terial 28 ispassed from the supply 25 under a roll29 and over the roll 3() yieldingly supported from the upright brackets31. From the roll 30 the strip of wrapper material passes down throughthe chute 32 and between the feed rolls 33, and the knife blades 34 tothe support 35. These parts are of well-known construction andoperation; The feed rolls are driven from a sprocket 37 mounted on theshaft 38. Sprocket 37 is connected with the sprocket 39 mounted on thefeed shaft 40 by means of the chain 41. The movable blade of the papercutter is loosely mounted on the upright rod 43 of the wrapper guidingconstruction. The movable cutter blade is actuated from the cam 45 (Fig.3) mounted on the main cam shaft 18. A cam roll 46 mounted on the arm 47travels in a cam path formed in the side of the cam 45. The arm 47 issecured to one end of a shaft 44 journaled in the machine frame. On theopposite end of the shaft 44 is a downwardly depending arm 48 connectedby means of a rod 49 with an arm 50 (Fig. 2) pivoted on a bracket 51.The movable cutter blade is provided with an arm 52 having a suitableconnection with the arm "50. These parts being of usual construction andmode of operation need no further description. The movable cutter bladeis actuated to sever the wrapper when the latter has been properlypositioned in front of the plunger 15.

The carrier 6 which first receives the unwrapped article and its wrappercomprises two sprocket wheels 54 and 55 connected by the chains 56. Thesprockets 54 are mounted on the shaft 38 which extends transverselyacross the machine and is journaled in the side walls thereof. Thesprockets 55 are 4mounted on a stud 58 secured in a bracket 59I (Fig.2). The rear end of shaft 38 extends beyond the machine frame andsupports a number of gears by which shaft `38 and other parts of themachine are driven. Shaft 38 is actuated .intermittently from a Genevagear construction. The Geneva gear -is driven from the main shaft 60 towhich power may be supplied in any preferred manner. The main shaft 60extends across the top of the ma` chine and on its front end carries ahand wheel 61; on its rear end it carries a clutch 62 operated by -ashifting device 63.

The main shaft 60 carries' a pinion 65 (Fig. 3) which meshes and drivesa gear 66 mounted on the .cam shaft 18. Onthe rear end of the cam shaftis mounted a pinion 67 which meshes with and drives a gear 68 mounted ona shaft 69 (Fig. 7) which also supports the constantly rotating element70 of the Geneva gear. The constantly rotating part 70 of the Genevagear carries two rolls 71 which are adapted to enter the slots 72 -ofthe intermittently rotating part 73 mounted on the stud 74. Securedtothe intermittently rotating part 7 3 is a gear 7 5 which meshes withthe gear 76 secured to the shaft 38. Thus intermittent movements areimparted to the shaft 38 and to the carrier 6.

On .the carrier 6 is mounted the series of equally spaced pockets 9;each pocket con' siss of two walls (Fig. 1), a fixed wall 78 and ayieldingly mounted wall 79. The pocket walls are supported from bracketswhich rise from a base 80 secured to the sprocket chain 5G. In orderthat the pockets of carrier 6 may be brought into proper alinement withthe pockets of the other carriers, the sprocket wheels 54 and 55 areprovided with the four-armed pocket guides 81 which are arranged on theshaft 38 and stud` 58 with the sprocket wheels. On the outer end of eacharm of the pocket guides 81 is a notch 82 adapted to receive a series ofequally spaced lugs 83 secured to the inner sidfe of the sprocketcha-ins 56. This construction permits the' pockets of carrier 6 to bebrought into proper alinement with the' pockets of the other carriers.The alinement of the pockets is further provided for bythe adjustableconnection 84 between the shaft 38 and the free end of the stud 58.

Carrier 5 and its pockets 8 are constructed substantially. like carrier6 and its pockets 9. The pockets on the two carriers are correspondinglyarranged.. Carrier 5 comprises the sprocket wheels 86 and 87 connectedby the sprocket chains 88 which support the pockets 8. Sprocket wheels86` are mounted on a shaft 89 which extends across the machineand isjournaled in the side walls thereof.- Sprocket wheels 87 are mounted onthe stud 90 which is supported from the frame of the machine in the samemanner that, stud 58 is supported. An adjustment rod 91 connects shaft89 with the free end of. stud .90. -'The rear end of shaft 89 projectsbeyond .the frame of the machine and is provided with a gear 92 whichmeshes with and is driven by a gear 93A mounted on shaft38. Thus the.shaft 89 and carrier 5 are actuated intermittently and in timed relationwith the intermittent movements of shaft 38 and carrier' 6.

.Following the insertion of the unwrapped article and its wrapper in oneof the pockets 9 of carrier 6 by plunger 15, carrier 6 is actuatedtobring the pocket containing the partially lwrapped article opposite thecorresponding pocket in carrier 5, as indicated in Fig. 6. rThereuponthe carriers momentarily come to rest and the oppositely disposedfingers 95 (Fig. 9) are actuated to transfer the partially wrappedcompleting theA side folds of the wrapper.

Plungers 95 are arranged to reciprocate vertically, passing throughpocket 9 to eject the article therefrom, and insert it in pocket 8 andreturning to normal position below pocket 9. For this purpose plungers95 are mounted on the lower ends of vert-ically disposed slides 96mounted in top guides 97 and bottom guides 98, suitably supported fromthe frame of the machine. The upper ends of slides 96 are pivotallyconnected by links 99 with rocker arms 100 secured to the rock shaft102. Intermittent rocking movement-'s are imparted to the shaft 102 froma cam 103 mounted on the front end of the main cam shaft 18 by means, ofa lever 104 loosely mounted on the main 'driving shaft 60 and a link 105adjustably secured to an arm 106 depending .from the shaft102. The leverarm 104 carries a roll which travels in the cam groove 107 cut in theside of the cam 103. It will thus be seen that as the cam 103 rotatesthe slide 96 is intermittently verticallyY reciprocated.

The partially wrapped article is positioned in the pocket of carrier 5with the end extensions of the wrapper projecting beyond the ends of thepocket, as indicated at 109 in Fig. 8. The ends of the article areindicated by the dotted lines 110. It will be observed-that the wall 111of the pocket is substantially as long as the article to be Wrapped, butthat the Wall 112 is considerably shorter than the article. The reasonfor this discrepancy in the length ofthe =1 walls will presently appear.'When the partially wrappedv article has been inserted in the pocket incarrier 5 and the plungers 95 have returned to normal position, thecarriers are again actuated. This movement of the partially wrappedarticle carries it between the stationary end folders 114 by which theend extensions of the wrapper are folded at right angles to the lengthof the article. In the illustrated embodiment of the invention, the endfolders 114 are brushes, which are particularly adapted for use when thearticle is relatively wide and thin and the inner wrapper is tin foil.Ac-

cording to the size and construction of the article to be Wrapped andthe material of which the inne'r wrapper is composed, different types ofstationary end folders are employed. The brushes 114 are adjustablymounted in the ends of holders 115 secured to heads 116 supported by therods 117 from the brackets 118 (Fig. 9)l secured to' the frame of themachine.

Inasmuch as the ends of wall 112 of the' pocket are removed, it will 'beobvious that a proper end fold cannot ybe made by the staarticle duringthe passage -of the article past the end folders 114, fold breakers 120are arranged to follow after the article and come in contact `with theend extensions of the wrapper as they pass between the end folders 114,as illustrated in dot and dash lines in Fig. 8. These fold breakers 120(Fig. 1) are verticall arranged plates secured'to the lower en s ofdownwardly' extendin arms121 secured to a rock shaft 122 pivote inbrackets 123-rising from the top of the machine. Rocking movements areimparted to the shaft 122 from the cam 125 'mounted'on the cam shaft 18by a rod 126 with the periphery of the cam 125 by meansl of the coilspring 128 (Fig. 9) one end of which is secured to the shaft 122 and theother end of which is secured to the bracket 123. The fold breakers 120are normally in the position-shown in Fig. 1. The movements of the foldbreakers are so timed that when the carrier 5 beo'ins to move to carrythe article past theend folders 114, the fold breakers overtake thearticle so that the partial endfold is made against the fold breakers,as shown in dot and dash lines in Fig. 8.

When the partial end folds have been made and the-.fold breakers 120have been retracted to normal position, the pocket holding the partiallyWrapped article momentarily comes to rest, as indicated at 129 in Fig.8. During the next intermittent lmovement of the carrier, the article isforced between the inturned ends 130 of the yieldingly mounted movableendI folders 131. The movable end folders 131 are pivotally supported at132 on the heads 116 and are normally pressed inwardly to .the positionshown in Fig. 8 by springs 133. When the article has passed beyondthemovable end folders 131, the ends 130 thereof return .to normal positionand thereby fold the end extensions of the wrapper down flat against thewrapped surface of the article, as indoated at 134. This series ofmovements completes the folding of the wrapper about the article. Thewrapped article is now in condition for receiving the label.

The Wrapped article is discharged from l the carrier 5 by plungers 137'secured to vertically reciprocating slides 138 mounted to slide inguides 139 secured to the frame of the machine. The upper ends of slides138 are pivotally connected by links 140 with the arms 136 secured toshaft 102. In the preferred form of the invention there are as manypockets mounted on carrier 5 as there are pockets on carrier 6,therefore when the wrapped article is returned to carrier 6 it isreinserted in the same pocket in which it was originally positioned. If,however, there are fewer pockets mounted on carrier 5 than on carrier 6,the wrapped article will be received by a different pocket on carrier 6.

Previous to the transfer of the wrapped article from carrier 5 tocarrier6, a label is positioned between the .alined pockets. Any preferredconstruction of pa er feeding mechanism may be employed kor deliveringthe labels one at a time to the machine. The labels are taken from thepoint of delivery to the machine and transferred to the pointbetween thealined pockets where it will be engaged by 'the Wrapped article andcarried with it into the opposite pocket to thereby partially fold thelabel about the article. The label transferring means comprises aplatform 145 supported on a bracket 144 (Figs. 10 and 11) 'secured tothe lower end of a vertically arranged shaft 146 jour naled in a hub 147integral with a bracket 148 extending transversely of the left hand endofthe machine. The platform 145 is arc-shaped and is of such length thatwhile one end is positionin r a label between the alined pockets theother endv may act as a guide for .the incoming label delivered to themachine. In the illustrated embodiment of the invention, the labels aredeering means, and Fig. 10 shows the position of the platform as itholds the label in place to be engaged by the wrapped article as thelatter is transferred to the pocket of carrier 6. This movement throughan angle of 90 is imparted tothe shaft 146 which supports the platformbv means of a cam 1,51 mounted on the camshaft 18. The connectionsbetween the cam 151 and the shaft 146 comprise an arm 152 secured `tothe shaft 44 and carrying on its free end a roll which travels in a campath formed in the side of vthe cam 151. On the forward end'of the shaft44 is mounted a bevel gear155 which meshes with and drives a bevelpinion 156 secured to the upper end of the shaft 146. Thus the platformis moved intermittently in timedrelation with the movements of thecarriers 5 and 6.

When the platform has released a label between the alined pockets and ithas swung to position to receive the next incoming label, the turned-upedge 158 of an end extension 159 adjustably secured to the platformengages the label which has just been delivered to the machine andpresses it against the lateral side of an adjustable guide 160 securedto and extendin rearwardly from the front frame of t e machine. By thismeans the label is properly positioned on the platform. Thereupon theclamp arm 162 provided at its free end with a felt gripping means 163 isactuated to press and hold the labelrmly against the platform. The clamparm 162 is pivotally mounted at 164 on an ear 165 rising from thebracket 144. The clam arm 162 is actuated to hold the label against ltheplatform and to release the label by means of a cam 166 mounted on thetain shaft 18. The connections between the cam 166 and the clamp 162comprise 'a cam roll 167 carried by the upper end of a rod 168. The rod168 is bifurcated and straddles the cam shaft 18. The lower end of therod 168 (which is ad justable in length) is pivotally connected with ahorizontally disposed link 169 piv-y otally connected at its other endwith a boss 170 depending from the bracket 148. The link 169 is providedwith a lug carrying a pin 172 which is engaged in a groove ormed in acollar 173 loosely mounted on the shaft 146. Also engaged in the groovedcollar 173 is a pin 174 projecting laterally from the clamp arm 162.Thus the ,active part of the cam 166 serves to raise the clamp arm 162and release the label. This occurs when platform'145 and the label 150are in the position shown in Fig. 10. The clamp is depressed to hold thelabel against the platform by the force of gravity. Thus the roll 167 isheld in contact with the cam 166l by the weight of the parts connectedwith it.

The feeding mechanism for delivering the labels one at a time to themachine comprises a platform 175 upon which the labels are stacked,as'shown in Fig. 3. The platform 175 is mounted on the upper end of avertically arranged rack 176 engaged and operated by a spring-drivenpinion 177. This construction, which is supported from the front of themachine by a bracket 178, is well-known and requires no furtherdescription. The labels are pressed upwardly against the holding needle18() supported on an arm 181 adjustably secured in a bracket 182. Thelabels are stripped from the pile and delivered in the machine one at atimeV by a rubber, ratchet-controlled wheel 183 (Fig. 11) when the pawl184 is in engagement with the ratchet wheel 185. When the pawl 184 isout of engagement with the ratchet wheel. the rubber. wheel 183 travelsback and forth on the pile of labels without delivering them. The wheel183 is carriedl by the offset end of a llever 186 pivotally mounted onthe lower end of an arm 188 secured to the shaft 189 journaled inbrackets extendingfrom the top of the machine. The

wheel 183 is yieldingly held in engagement I lmachine. The crank 192'isconnected by a on a bracket 201. The rolls 198 are held in yieldingengagement with the rolls 197 by means of the spring 202. The rolls 198are driven in a counter-clockwise direction (viewing Fig. 3) and forthis purpose the shaft 193 is provided with a gear 203 which meshes witha gear 204 mounted on the shaft 199. The left hand end of the shaft 193carries a bevel gear 206 which meshes With a corresponding gear 207fixed on a shaft 208 journaled in the machine frame- The other end ofthe shaft`208 carries a sprocket wheel 209 which is driven by a secondsprocket wheel 210 mounted `on the cam shaft 18. The sprocket wheels areconnected by a chain 211. Proper tension is imparted to the chain by anidler sprocket 212 mounted on the stud 213. rllhus the feed rolls 197and 198 are driven intermittently in timed relation with the othermoving parts of the machine.

The feed rolls 197 and '198 deliver the label in position to be clampedagainst the platform 145. Labels for different sizes of articles vary inlength. Some labels are ol' such length that it is not expedient that.they pass entirely through .the feed rolls before they are gripped andswung into position between the alined pockets. Then this is the case,and in order that the labels may move freely from between the feedrolls, the shaft 193 is provided with a cam 215 (Fig. 4), the activepart of which is adapted to contact with a roll 217 mounted on the shaft199 and thereby swing the shaft 199 downwardly and the rolls '198 out ofcontact with the label and the rolls 197. When the active part of thecam 215 has passed out of engagement with the roll 217, the spring 202returns the shaft199 to normal position in engagement with the rolls197. As the labelis swung from the point of delivery to the point whereit is positioned between the alined pockets, the free, unsupported endof the label passes between upper and lower guide rods 218 and 219 (Fig.11). The feed rolls 197 and 198 deliver the labels to the machinebetween an upper guide 220 having an up-turned forward end 221 and alower guide 222. The swing of the platform into position to receive thelabel and into position to deliver the label between the alined pocketsis dethe label 150 (see Fig. 18) and carries ity with it into thereceiving pocket. This movement partially folds the label about thearticle, las indicated in dot and dash lines. Carrier 6 is then actuatedto ,bring the vpartially labeled article to the position indicated inFig. 19 with the unfolded end of the label extending outwardly andresting on a support 226. While the label is in this position, a pasteapplying roll 227 mounted in the lower open end of a paste pot 228 isbrought into engagement with the end of the label. The paste pot 228 isadjustably supported on the bell-crank arm 229 (Fig. 1) secured to theshaft 230. The other arm 231 of the bellcrank is pivotally connectedwith the lower end of a rod 232, the upper bifurcated end 233 (Fig. 3)of which straddles the cam shaft 18 and carries a roll in engagementwith the cam 234 mounted on the cam shaft. The paste applying device isthus actuated in timed relation with the other parts of the machine toapply paste to the label when the latter occupies vthe position shown inFig. 19.

As the paste pot is swung into paste applying position the ratchet wheel236 'travels over the pivotally and yieldingly mounted rack 237. Theconstruction is such that the movement vof the paste pot into pasteapplying position depresses the rack 237, and the engagement oftheratchet wheel with the rack teeth causes the pasteroll 237 to beturned to expose a fresh surface of paste to the label. The pawl 238prevents the rotation of the paste roll in the opposite direction. Thespring 239 (Fig. 3)'returns the rack237 to normal position. Theconstruct-ion and mode of operation of the paste applying device are oldand well-known.

lll)

After the paste has beenA applied to the label, the carrier 6 is againadvanced and then comes to rest in the position shown in Fig. 20. As thepartially labeled article is-swung in to this position, the outstandingend of the label encounters a yieldingly mounted drag 240 which servesto draw the label tightly about the article. When the carrier has cometo rest, .plungers 241 secured to the lower ends of the slides 138 areactuated to transferthe partiallylabeled article into the oppositealined pocket 10 of carrier 7, thereby completing the labeling of thearticle.

In order that the glue may set suiiciently to permit the wrapped andlabeled article to be ejected from carrier 7, the carrier rotates in thedirection indicated by the arrow in Fig. 6 to the point of deliverywhich is indicated at 248. Carrierv 7 is driven intermittently in timedrelation with the movcments of carriers and 6, and for this purposecarrier 7 is mounted on a shaft 245 which extends transversely of themachine and carries on its rear end a gear 246 which meshes with and isdriven by a gear2el7 mounted on the shaft 88. Carrier 7 is provided withonly four pockets vwhich are mounted on a hub 248. The manner ofmounting the pockets 10 on carrier 7 is substantially' the same as themanner of mounting the pockets on carriers 5 and 6, that is to say, onewall of the pocket is fixed and the other is yielding.

Vhen the wrapped and labeled articles are brought to the point ofdischarge 243 6) they are discharged from the carrierby a pair ofhorizontally reciprocat ing plungers 250 mounted on slides 251reciprocating in guides l252. The plungers-x 250 are reciprocated fromthe front rocker arm 100 through a vertically arranged rod 2541 (Fig.5), the upper end of which is pivotally connected with the rocker armand the lower end of which is pivotally connected with an arm 255,secured to a shaft 256 which extends transversely of the machine, and isjournaled in the front and rear walls thereof. Arms 257 secured to anddepending from the shaft 256 are connected by links 258 with therearends of the slides 251. Thus the horizontally reciprocating plungers250 are actuated in timed relation with the vertically reciprocatingplungers. 4

The wrapped and labeled articles discharged from carrier 7 are receivedvby a platform 260 (Figs. 13 and 14) mounted on a lever arm 261 securedito a shaft 262 I extending transversely across the machine.

On the rear end of the shaft 262 is mounted a crank 2655. `The shaft 262is oscillated in timed relation with the movements of the other parts ofthe machine from a cam 265 (Fig. 7) mounted on the cam shaft 18. A camroll 266 mounted on an arm 267 pivoted at 268 .travels in a path formedin the side of cam 265. The vfree end of arm 267 is connected with crank263 by a rod 269. The receiving platform 260 is arranged to deliver thewrapped and labeled articles in the bottom of the stacking chute 271.

The stacking chute 271 `is composed of two sides 272 and a botto-m 273which are obliquely arranged, as shown in Fig. 14;. The bottom 273 issupported from the bracket 274 and the sides 272 are adjustablysupported from the rods 277. In the lower ends of the side walls 272 ofthe stacking chute are pivotally and yieldinely mounted gates or articlesupports 2' 5. Springs 276 act to press the upper ends 278 of thesupports inwardly to keep the -plungers 137 are actuated to reinsert thestacked articles in the chute, as indicated in Fig 15. When thereceiving platform., 26() is actuated to insert a freshly wrapped' andlabeled article in the bottom of 'the chute, the supports 275 are forcedoutward- )Vixen the platform 260 with its article has passed beyond theupper ends 278 of the supports 275, the springs 276 act to return the4supports to normal position to prevent the egress of the newly insertedarticle.' The length of the platform is ,such that it passes freelybetween the supports while they are in normal position.

The operation of the improvedfwrapping machine has been indicated inconnection with the description of the construction of the various partsof the machine. The passage of an article through the machine and thevarious wrapper folding operations will be briefly recapitulated Theunwrapped article is indicated at 280 (Fig. 6) and the wrapper in whichit is to be enclosed is indicated at 281. The 'forward movement ofplunger 15 inserts the article and wrapper in the alined pocket 282 of.carrier 6, thereby partially foldingr the. wrap r about the article, asshown in F ig.` 1 6. larrier 6 is then actuated and the article 280comes to rest at 288 (Figs. 6 and 17).' As the article passes from point282 to4 point 283, the outstanding side of the wrapper passes under ayieldingly mounted `guide 285 by which the side' eX- tension 284 (Fig.17) of the wrapper is bent downwardly. When the carrier' has lcome torest, the plungers are actuated to in- Cil4 sert the article in theoppositely disposed dicated in Figs. 8 and 18,A whereby the endextensions of the wrapper are folded down against the Wrapped side ofthe. article. the finish of the end folding operations, the Wrappedarticle occupies the position indicated at 287.' The label 15() having;been positioned under the wrapped article, the

article and at the same ltimethe label in pocket 288 of carrier 6, whichis thet same f pocket in which the plunger 15 first in-V serted the`article. The next intermittentv movement of carrier 6 brings thewrapped and partially labeled article to position 289 (Fig. 6), which isthe position shown in Fig. 19. During the momentary dwell of thecarrier, paste is applied to the out- Standing end of the label.Thereupon the article is brought to position 290, this being theposition shown in Fig. 20.v )Vhile the carrier is at rest, the plungers240 are actuated to insert the article in the oppositely disposed pocket291,4 thereby completing the foldingv ofthe .label about the wrappedarticle, as indicated in dot and dash lines l,in Fig. 20.
